How Often Should Engine Oil Be Changed for a Car That Is Not Driven for a Long Time?

[Grant]

For cars that are not driven for a long time, the engine oil should be changed every 6 to 8 months. The method for changing the engine oil is as follows: 1. Lift the car, remove the protective plate, and place a container under the oil drain screw; 2. Unscrew the oil drain screw, use an air gun to blow for two minutes at the oil filler port, then tighten the oil drain screw after draining and wipe it with a tissue to check for oil leaks; 3. Reinstall the protective plate and lower the car, then add engine oil through the filler port. Precautions for changing engine oil: 1. Perform the change while the engine is warm to ensure the old oil is drained as thoroughly as possible; 2. Add engine oil and ensure the amount is appropriate; 3. After adding the oil, start the engine and check all components for oil leaks. Run the engine for 3 minutes to confirm the oil level is at the normal mark.
